[Solved] CCleaner - Change App-Icon
I don't know in what format the app-icon of CCleaner is.
So I extracted the icon from the EXE with an icon editor.
Here is the new app-icon in ICO format:
The icon looks smaller than the others, but it also contains a 256x256 pixels icon.
Cool, the app-icon is now shown and has a transparent background (so the ICO was used).
